Hi Ganesh,
yeah, first step of CMake: done!

Some internet searching revealed that you are not the first one to have
this problem. But I was not able to quickly find a general solution.
There was not even a obviously related bug in CMake's bug tracker.
I'd suggest to set the permission by yourself.
1. Rund dunecontrol and add --only=dune-common and use "configure"
instead of "all"
2. Set the permission for dune-common/build-cmake that you are allowed
to read and write inside the folder and all subfolders
3. Re-run dunecontrol, again with --only=dune-common and use "make"
instead of "all"
4. If that works for dune-common, you can proceed with dune-geometry,
dune-grid and so on.

I know, this is sub-optimal, but to get it running, it could be enough.

It is related to Cygwin, as I never had file permission issues with
Visual C++ and CMake. I only had compiler issues...

Bye
Christoph
